Abstract

Link adaptation is an essential part of wireless communication in order to guarantee required QoS in dynamically varying channel by changing the transmitter parameter according to channel condition in order to utilize spectrum must efficiently. This work proposes a noble producer for link adaptation with adaptation of carrier spacing of OFDM based communication system according to the channel condition. This method of link adaptation may mitigate the need of perfect carrier frequency offset (CFO) estimation at the receiver side. The simulation result shows the switching levels for different types of channel described by stand ford University Interim (SUI) models for IEEE 802. 16 based system using fixed threshold based algorithm.
